Getting speaker fill working in Windows 10 is proving a nightmare.
The driver supplied by the motherboard manufacturer is missing the feature. The generic HD audio drivers supplied by Windows 10 support speaker fill but there's this weird delay between front and rear channels and the audio is distorted in the rear channels.
Now trying the generic drivers from Realtek's website...

im trying to figure out how to start postgresql on boot.
it looks like all i need is enable & start postgresql.service right?
But threre is one problem.
user@server:/etc/systemd/system$ pg_ctl status
pg_ctl: server is running (PID: 19670)
/home/user/postgresql/bin/postgres

user@server:/etc/systemd/system$ sudo systemctl status postgresql.service
● postgresql.service
Loaded: masked (/dev/null; bad)
Active: inactive (dead)
Whats going on ? =P
 
Nathan Osman
Nathan Osman
Does pg_ctl just check for the pidfile or does it actively communicate with the server to verify it is running?
If systemd is reporting the service as masked, it is disabled and will not start.

Belgium always makes new words when they adapt something from english. We Dutch just adopt the english word (sometimes altering 1 or 2 letters due to rules on syllables)

Q: Ask for username and password on 18's login screen

lonixI'm using the latest Ubuntu 18.04 LTS bionic. When I login it shows my username and I just need to type a password. I don't want usernames to be shown. I want to be forced to type a username and password. How do I do that? All I found is info for old versions or lightdm (18 uses gdm).

@rinzwind if gdm crashes you cannot use tty3
tty's are only created on demand
by gdm3
so only way to fix this is using root prompt from grub
 
Rinzwind

@Benny original of what? BIOS? doubt it... BIOS update is always "old" BIOS + bugfixes. It hardly ever includes new content since your board does not have new features.
@Videonauth eew. That's bad design in my opinion

Anyone here who might be able to help me out? I try the following, I have in a game which I modded a list of missing assets and now i would like to printout in terminal their asset number behind a given link to the steam workshop, so that I can open the links in browser and suscribe to the assets without copy and pasting to much 
$ cat Player.log | grep 'Asset not found'
[LSM] Asset not found: 763472782.dong_Data
[LSM] Asset not found: 775509816.Yellow Line 01_Data
[LSM] Asset not found: 1098938808.R69 Tamurakoma Sign_Data
is how it looks basically, applying awk to print the 5th element gives me what i want but it still has a dot. and useless information 
$ cat Player.log | grep 'Asset not found' | awk '{print $5;}'
763472782.dong_Data
775509816.Yellow
1098938808.R69
1098938808.R69
904028991.ra64_SatelliteDish01_Data
904028991.ra64_SatelliteDish03_Data
904028991.ra64_SatelliteDish04_Data
all i need now is a way to get those numbers in front in an echo "https://steamcommunity.com/sharedfiles/filedetails/?id=<NUMBER_HERE>" for all numbers
anyone? @dessert? 
$ grep 'Asset not found' Player.log | awk '{print $5;}' | grep -oE '^[0-9]+'
763472782
775509816
1098938808
1098938808
904028991

this is how far i got but now no clue how to get it into the output
NVM figured it out
for number in $(grep 'Asset not found' Player.log | awk '{print $5;}' | grep -oE '^[0-9]+'); do echo "https://steamcommunity.com/sharedfiles/filedetails/?id=$number"; done

> I took the view that, if convergence was the future and we could deliver it as free software, that would be widely appreciated both in the free software community and in the technology industry, where there is substantial frustration with the existing, closed, alternatives available to manufacturers. I was wrong on both counts.

@Videonauth for i in $(grep -oP '.*Asset not found: \K\d*' <test); do echo "https://steamcommunity.com/sharedfiles/filedetails/?id="$i; done
or with parallel: 
parallel echo "https://steamcommunity.com/sharedfiles/filedetails/?id="{} ::: $(grep -oP '.*Asset not found: \K\d*' <test)
provided the file name is “test”, needless to say ;P
 
Videonauth
Videonauth
nice a shorter version of what i produced there :)
but wouln't that as well print the asset not found part?
 
terdon
terdon
@Videonauth that's what sed is for:
You might also want to pipe through uniq though:
Well, sort -u anyway
By the way, @dessert the .* at the beginning of your regex doesn't change anything. You're ignoring everything before the match anyway, so you could just do grep -oP 'Asset not found: \K\d*
Although \d+ would be safer since \d* also matches 0 digits.
</nitpicking>
 
Videonauth
Videonauth
ok have to take those apart, need to understand :)
 
terdon
terdon
5:46 PM
The basic thing is sed -n which means "don't print unless I tell you to". Then you have a substitution s|old|new|p. The p means "print if the substitution works". So it will only print on lines it managed to run the substitution on.
 
Videonauth
Videonauth
ok and youre using | as delimiter instead of / to prevent the mountain building right?
 
terdon
terdon
yep
And -E gives us the + for "one or more" and allows the use of parentheses to capture stuff without needing to escape them.
 
Videonauth
Videonauth
question is sed -E option the same as grep -E ?
 
terdon
terdon
Basically, yes. 
$ man sed | grep -A2 -- -E,
       -E, -r, --regexp-extended

              use extended regular expressions in the script (for portability use POSIX -E).
$ man grep | grep -A2 -- -E,
       -E, --extended-regexp
              Interpret PATTERN as an extended regular expression (ERE, see below).

@Videonauth too late :D 
<test awk '/Asset not found/{print gensub(/.*: ([0-9]+)\..*/,"https://steamcommunity.com/sharedfiles/filedetails/?id=\\1","g")}'
that’s much better: only for the lines with Asset not found save the number in group 1, replace the whole line with the url followed by the content of group 1 and print the resulting line.
"g" to replace globally is actually useless, could be simply 1 to only replace the first occurence
